Step-by-step math

Every number below is computed from the input, nothing is looked up.

1. RGB ÷ 255
```
R = 0.7255
G = 0.9725
B = 0.8118
```

2. max, min, Δ

max = 0.9725
min = 0.7255
Δ = max − min = 0.2471

3. L
```
L = (max + min) / 2 = 0.8490 = 84.90%
```

4. S

S = Δ / (1 − |2L − 1|) = 0.8182 = 81.82%

5. H

max is G → H = 60° × ((B − R) / Δ + 2) = 60° × ((0.8118 − 0.7255) / 0.2471 + 2) = 140.95°

6. HSL
```
hsl(140.95 81.82% 84.90%)
```
